At our side we also add this problem that the pmix lib was compiled with munge support. We solved it by setting this environment variable:
 *  export PMIX_MCA_psec=native  of export PMIX_MCA_psec=none

Regard,

Hi,

When using slurm-20.11.7 compiled with pmix-3.2.3,  and job is submitted like below :

srun -N 1 -c 2 --pty /bin/bash

on the allocated compute node, when I execute the below command, I get the PMI error with return value -46

mpirun -c 2 /bin/hostname

A requested component was not found, or was unable to be opened.  This

means that this component is either not installed or is unable to be

used on your system (e.g., sometimes this means that shared libraries

that the component requires are unable to be found/loaded).  Note that

PMIX stopped checking at the first component that it did not find.

Host: cnode9

Framework: psec

Component: munge

It looks like pmix_init failed for some reason; your parallel process is

likely to abort.  There are many reasons that a parallel process can

fail during pmix_init; some of which are due to configuration or

environment problems.  This failure appears to be an internal failure;

here's some additional information (which may only be relevant to an

PMIX developer):

   pmix_psec_base_open failed

   --> Returned value -46 instead of PMIX_SUCCESS
